Empty pages marked corrupt

I run rman and it shows some blocks as corrupted; when I run dbv all
the blocks corrupt show under empty pages.
When I do
select * from dba_extents
where file_id = 25 and
corrupt_block_no between block_id and block_id+blocks-1
all corrupted blocks are in a table which is empty (0 rows).
I dropped the table , recreated it, but these blocks still come out as
corrupt.

Will these empty pages corruption create any problems for me in
future?
How can I get rid of them, rman recoverblock somehow is not working
for me?
